玉米地下害虫与玉米茎基腐病化学-生物协同防控技术及区域适配性分析
A Study on Integrated Chemical-Biological Synergistic Control Technology for Underground Pests of Corn and Corn Stem Base Rot and Regional Adaptability Analysis
摘要
Abstract
Corn underground pests and corn stem base rot are important disease and pests that restrict corn production in China.Different production areas show unique occurrence patterns and damage characteristics due to differences in ecological conditions.Focusing on two typical ecological areas in the central and southern regions of Ningxia,namely Yanchi County(sandy soil area)and Haiyuan County(loess area),based on the research results of the main corn-producing areas such as Heilongjiang,Jilin and Ningxia,a systematic review was conducted on the species composition,damage characteristics and occurrence patterns of underground corn pests(such as grubs,cutworms,wireworms,mole crickets,etc.)and corn stem base rot in sandy soil areas and loess soil areas.By integrating the technological experiences of multiple production areas(major corn production areas such as Heilongjiang,Jilin and Ningxia),and combining the key points of agricultural control,physical control,chemical control and biological control technologies,the effectiveness of the"chemical seed dressing+microbial drip irrigation"synergistic control technology was verified through field experiments.The results showed that in the sandy and windy soil area of Yanchi County,when 48％bromocyanamide+18％pyrazole ether was used for seed dressing combined with microbial agent No.3 drip irrigation,the control effect of underground pests reached 66.71％,the control effect of corn stem base rot reached 56.58％,and the yield increased by 8.84％compared with the control.In the loess area of Haiyuan County,by using a combination of the same pesticide and microbial agent No.9 for drip irrigation,the control effect of underground pests reached 82.07％,the control effect of corn stem base rot reached 67.51％,and the yield increased by 11.16％.The research provides technological support for the precise prevention and control of corn pests and diseases in the central and southern regions of Ningxia.关键词
